As you may already know, Apple has already pushed another update for the iOS which is now officially called iOS 5.1.1. And of course, jailbreak users are probably wondering if the latest iOS version is jailbreak safe. Well, MuscleNerd has confirmed that iOS 5.1.1 can indeed be jailbroken, albeit tethered only, using the latest version of Redsn0w. As per usual, we will provide the guide on how to jailbreak iOS 5.1.1 using Redsn0w.NOTE: This tutorial is only applicable for A4 devices which means that if you have an iPhone 4S, iPad 2 or the 3rd-gen iPad, we recommend that you stay on the firmware version you are on since you will not be able to use this guide. Also take note that this is a tethered jailbreak which means that each time your device gets shut down or rebooted, you will need to run it over Redsn0w, so it become usable again.

Steps on How to Jailbreak iOS 5.1.1 on iPhone, iPad & iPod touch Using Redsn0w:

To use this tutorial, you will of course need to be in iOS 5.1.1. To update, you may update using OTA or you can just download the iOS 5.1.1 IPSW files and use it to update your iPhone, iPad or iPod touch. Be sure that you backup your files before upgrading firmware.

You will also need to download the iOS 5.1 IPSW (not iOS 5.1.1) file which corresponds to your device.

Download Redsn0w 0.9.10b8b either for Mac or Windows, whichever is applicable in your case. Extract the downloaded files in your preferred directory.

Launch Redsn0w.exe from the files you have downloaded.

Click on the "Extras" button and then the "Select IPSW" option.

Now point Redsn0w to the iOS 5.1 IPSW file that you have downloaded in Step 2. Redsn0w will then identify the IPSW file and after that click Back.

Click Jailbreak. In this step, check the Install Cydia option and click Next.

At this point, Redsn0w will ask you to place your device into DFU Mode. So if you know the process, you can perform it now or simply follow the on-screen instructions.

Once DFU Mode has been detected, Redsn0w will take care of the rest. The rest of the jailbreak procedure will happen on your device. Just be sure not to touch or disconnect your iDevice while the process is still running.

Since this is a tethered jailbreak, you will need to run Redsn0w each time that your device gets rebooted. To do this, simply launch Redsn0w, click Extras > Just Boot.
